What is DownTek

What is DownTekWhat is DownTek™?

We know that down is the single best insulation that exists. However, it has a problem when it gets wet. Mother Nature designed down clusters to trap pockets of air. Those pockets are what insulate, keeping you warm and comfortable. Then moisture comes along and deflates the pockets of air, eliminating down's ability to insulate. That is why you see those geese shake off the rain! Enter DownTek™ Water Repellent Down. DownTek™ shields those insulating-air-trapping-clusters from all wet things.
